After installation of K2 component he is “empty” – it doesn’t contain any content. What may slightly disappoint some people – especially if you want to replace the standard articles those from K2. Fortunately component K2 is equipped with a button to import.
Using this button allows you to import all categories and articles from Joomla!’s core content component (com_content) into K2! If this is the first time you import content to K2 and your site has more than a couple of thousand articles, the process may take a few minutes.
Note: If you have executed this operation before, duplicate content may be produced!
Unfortunately, you can not select which categories or specific articles will be imported – so you may need to remove unwanted content after the import process.
If you want to import content from another source, for example : from a CSV-file, you have to use additional extension for it like Import Tool for K2.
